HEATING DEVICE FOR WAGON-TIRES AND S TOVES.

SPECIFICATION forming part of Letters Patent No. 630,411, dated August8, 1899.

Application filed May 4, 1899. Serial No. 715,556. (No model.)

To all whom it may concern.-

Be it known that I, CLARK ROBINSON, aciti- 'zen of the United States ofAmerica, residtains to make and use the same, reference being had to theaccompanying drawings, and

to the figures of reference marked thereon,

which form a part of this specification.

This invention relates to tire-heaters of that class using oil as fueland burner and vaporizing pipes as means for consuming the oil.

The object of the invention is by anovel construction and arrangement ofparts to materially reduce the cost of construction of a tire-heater ofthis character, While retaining its full effectiveness and increasingits rapidity and convenience in use.

The invention will be hereinafter fully described and claimed. i

Referring to the drawings, in which the same numerals of referenceindicate corresponding parts in the several views, Figure 1 is aperspective view of my new and i111 proved tire-heater. Fig. 2 is acentral vertical sectional view of the same. Fig. 3 is a sectional viewthrough one of the supportingbrackets.

The oil passes from an elevated reservoir 8 through the supply-pipe 2,the horizontal portion of whichis arranged centrally within a cylinderor retort 1, and said portion within the retort is formed with a seriesof small apertures 2, through which the oil drops to the bottom of theretort or cylinder, the inner end of said supply-pipe 2 being closed bya cap. The ends'of the retort or cylinder are also closed by caps, asshown.

The straight retort or cylinder 1 is connected centrally by a coupling 9with a straight burner-pipe 3, extending in a line beneath the retort.This retort l and burner 3 together form a straight vaporizer. The ends3 of the burner-pipe extend upward at right angles and connect at theirupper ends with the circular burner or tire-heating pipe 6, the

latter being thus raised above the plane of the burner-pipe 8. In someinstances I may prefer to omit the circular burner-pipe 6. It is alsoobvious that said burner-pipe 6 could be lowered to a position on alevel with the burner-pipe 3.

5 5 indicate the supporting-brackets, which are formed with the upperretort-bearings 5, which receive the retort or cylinder, and withintermediate bearings 5, which receive the burner-pipe 3 to hold andsupport the latter in position below the retort, said brackets alsohaving rectangular openings 5 to receive and support the long shallowpan 4 in line below the burner-pipe 3. The object of this pan is tocatch the drippings of oil from the burner-pipe 3, and by lighting theoil collected in this pan before turning on the flow of oil from thereservoir 8 the retort or cylinder is made hot before the oil begins toflow into it from the reservoir, thus effecting a saving and causing thegenerator or retort to operate at once. The oil being then turned onflows into the perforated supply-pipe 2 and drops through theperforations therein upon the hot bottom of the retort, when thevaporization at once begins. The vapor thus generated mixes with therequisite quantity of air, which enters the retort through an opening 10in one of its end caps, passes down through the central coupling 9 intothe bu rnerpipe 3, and a portion of it burns at the flameopenings in thelatter, while the bulk of the vapor thus generated passes on into thecircular burner-pipe 6, over which the tires are suspended, entering thesaid circular burnerpipe from both ends of the burner-pipe 3. It will benoted that the supply-pipe 2 passes through the opening 10, andtherefore said opening is a little larger than the pipe to permit acertain quantity of air to pass into the retort,

By elevating the circular burner-pipe 6 above the burner-pipe 3, asshown, no oil can get into said circular pipe. Therefore when the oil inthe burner-pipe 3 begins to generate it forces the gas or vapor to riseinto the circular burner-pipe 6, where it burns.

It will be seen that by placing the retort across the circle of thetire-heating pipe 6, instead of forming it in a circle or square, I savealmost one-half the cost of making the fil1 the pipes in the old way.

A suitable cover-such as described in my prior patent, No. 527,51, datedOctober 16,

, 1894-may be employed, and the heater may be set directly upon theground or upon a suitable base.

By omitting the circular burner-pipe the straight vaporizer, consistingof theretort and burner-pipe 3, with the supporting-brackets anddrip-pan, could be used as a heating device for stoves or otherpurposes.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is-

1. A tire heater, comprising a circular burner, astraight retortextending across the circle of said burner and means for supply i ng oiland air to said retort,- and the straight burner extending in linebeneath and communicating with the retort and also with the circularburner, and arranged below .the plane of said circular burner,substantially asand for thepurpose set forth.

2. A tire heater, comprising a circular burner, a straight retortextending across the circle of said burner, and means forsupplynicatingwith the circular burner, substantially as set forth.

3. A tireheater, comprising a circular burner, a straight retortextending across the circle of said burner, and means for supplyingair.and oil to said retort, the straight burner extending in line beneathand communicating with the retort, and also with the circularburner,an'd arranged below the plane of said circular burner, and thelong dripj'p'an positioned in line beneath the straight I. burner, forthe purpos'eispecified; substantially as set forth.

4. The herein-described tire-heater, eonf sisting of the circularburner, the straight re-. tort extending across the circle of the same,the-supply-pipe leading from a suitable reservoir and extending insidethe retort; and 1 formed therein with'the smallfeed-openings; thestraight burner-pipe extending in linebe- 1 neath the straight retort,below the plane of the circularburner, communicating centrally with theretort and having the upwardly-ex- 3 tending ends communicating with thecircular burner, and the drip-pan mounted in line beneath the straightburner-pipe, for the purpose specified; substantially as set forth.

= In testimony whereof I afli-x my signature in presence of twowitnesses. ing oil and air to said retort, the straight burner extendingin line beneath the straight retort below the plane of the circularburner, communicating centrally with the retort and having theupwardly-extendin g ends'commu- CLARK ROBINSON.
